This commit adds two pieces. The first is a small set of documentation providing
instructions on how to get setup to run context examples. This will require a download
similar to how Kibana works for some of the examples. The second is an ingest processor
example using the downloaded data. More examples will follow as ideally one per PR.
This also adds a set of tests to individually test each script as a unit test.
As part of #32608 we made sure that the fully qualified index name is taken from the query shard context whenever creating a new `QueryShardException`. That change introduced a regression as instead of setting the entire `Index` object to the exception, which holds index name and index uuid, we ended up setting only the index name (including cluster alias). With this commit we make sure that the index uuid does not get lost and we try to lower the chances that a similar bug makes it in another time. That's done by making `QueryShardContext` return the fully qualified `Index` (which also holds the uuid) rather than only the fully qualified index name.
This change consolidates all the logic for generating a FunctionReference (renamed from
FunctionRef) from several arbitrary constructors to a single static function that is used at
both compile-time and run-time. This increases long-term maintainability as it is much
easier to follow when and how a function reference is being generated. It moves most of
the duplicated logic out of the ECapturingFuncRef, EFuncRef and ELambda nodes and
Def as well.
This modifies Def to use a Map<String, LocalMethod> to look up user-defined methods at runtime
instead of writing constant methodhandles to do the reverse lookup. This creates a consistency
between how LocalMethods are looked up at compile-time and run-time. This consistency will allow
this code to be more maintainable moving forward. This will also allow FunctionReference to be
cleaned up in a follow up PR.
Renames existing methods in PainlessLookup. Adds lookupPainlessClass,
lookupPainlessMethod, and lookupPainlessField to PainlessLookup. This consolidates
the logic necessary to look these things up into a single place and begins the clean up of
some of the nodes that were looking each of these things up individually. This also has
the added benefit of improved consistency in error messaging.
This commit adds a boolean system property, `es.scripting.use_java_time`,
which controls the concrete return type used by doc values within
scripts. The return type of accessing doc values for a date field is
changed to Object, essentially duck typing the type to allow
co-existence during the transition from joda time to java time.
* Upgrade to `4.1.28` since the problem reported in #32487 is a bug in Netty itself (see https://github.com/netty/netty/issues/7337)
* Fixed other leaks in test code that now showed up due to fixes improvements in leak reporting in the newer version
* Needed to extend permissions for netty common package because it now sets a classloader at runtime after changes in 63bae0956a
* Adjusted forbidden APIs check accordingly
* Closes#32487
Renames and removes variables from PainlessMethod to follow the new naming
convention. Generates methodtypes at compile-time instead of using a method at run-
time. Moves write method to MethodWriter.
This commit fixes the painless compiler classloader to know about the
classes from the script context. This fixes an issue when a custom
context is used from a plugin which caused a ClassNotFoundException for
the script class and its factory classes.
PainlessMethod was being used as both a method and a constructor, and while there are
similarities, there are also some major differences. This allows the reflection objects to be
stored reducing the number of other pieces of data stored in a PainlessMethod as they are
now redundant. This temporarily increases some of the code in FunctionRef and
PainlessDocGenerator as they now differentiate between constructors and methods, BUT
is also makes the code more maintainable because there aren't checks in several places
anymore to differentiate.
The error tests for hex values previously used a random string of
digits, but this could be a valid hex value. This commit changes these
tests to use a fixed invalid hex value.
closes#32370
MethodType can be computed at compile-time rather than run-time. This removes the
method that collects MethodType at run-time from a PainlessMethod since is it no longer
necessary.
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.
This commit changes the randomization to always create an index with a type.
It also adds a way to create a query shard context that maps to an index with
no type registered in order to explicitely test cases where there is no type.
There are two scenarios where a http request could terminate in the cors
handler. If that occurs, the requests need to be released. This commit
releases those requests.
Removes the variables name, clazz, and type as they are unnecessary. Renames
staticMembers -> staticFields, members -> fields, getters -> getterMethodHandles, and
setters -> setterMethodHandles.
Removing some dead code or supressing warnings where apropriate. Most of the
time the variable tested for null is dereferenced earlier or never used before.
Implements a static function in PainlessLookupBuilder that contains all the logic related
to Whitelist. PainlessLookupBuilder is available for use in loading from methods beyond
Whitelist now.
* Test `handler` must release buffer the same way the replaced `org.elasticsearch.http.netty4.Netty4HttpRequestHandler#channelRead0` releases it
* Closes#32289
This finishes the updating the methods in the PainlessLookupBuilder to the new naming scheme. Mechanical change. Methods include the ones used for copying members in the inheritance hierarchy, calculating shortcuts, and setting the functional interface.
This adds the ERR metric to the provided xContent parsers in the module and the
high level rest client registry. Also adding integration tests to make sure the
metric is correctly registered and usable from the client.
Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.
Closes#15731
The notion of "quality" is an overloaded term in the search ranking evaluation
context. Its usually used to decribe certain levels of "good" vs. "bad" of a
seach result with respect to the users information need. We currently report the
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.
This is largely mechanical change that cleans up the addConstructor, addMethod, and
addFields methods in PainlessLookup. Changes include renamed variables, better error
messages, and some minor code movement to make it more maintainable long term.
* INGEST: Extend KV Processor (#31789)
Added more capabilities supported by LS to the KV processor:
* Stripping of brackets and quotes from values (`include_brackets` in corresponding LS filter)
* Adding key prefixes
* Trimming specified chars from keys and values
Refactored the way the filter is configured to avoid conditionals during execution.
Refactored Tests a little to not have to add more redundant getters for new parameters.
Relates #31786
* Add documentation
* INGEST: Make a few Processors callable by Painless
* Extracted a few stateless String processors as well as the json processor to static methods and whitelisted them in Painless
* provide whitelist from processors plugin
Currently the ranking evaluation response contains a 'unknown_docs' section
for each search use case in the evaluation set. It contains document ids for
results in the search hits that currently don't have a quality rating.
This change renames it to `unrated_docs`, which better reflects its purpose.
This removes some extraneous naming syntax and makes clear the meaning of certain
naming conventions without ambiguities (stricter) within the lookup package. Purely
mechanical change. Note this does not cover a large portion of the
PainlessLookupBuilder and PainlessLookup yet as there are several more follow up PRs for these incoming.
* Add basic support for field aliases in index mappings. (#31287)
* Allow for aliases when fetching stored fields. (#31411)
* Add tests around accessing field aliases in scripts. (#31417)
* Add documentation around field aliases. (#31538)
* Add validation for field alias mappings. (#31518)
* Return both concrete fields and aliases in DocumentFieldMappers#getMapper. (#31671)
* Make sure that field-level security is enforced when using field aliases. (#31807)
* Add more comprehensive tests for field aliases in queries + aggregations. (#31565)
* Remove the deprecated method DocumentFieldMappers#getFieldMapper. (#32148)
This change cleans up the addPainlessClass methods by doing the following things:
* Rename many variable names to match the new conventions described in the JavaDocs
for PainlessLookup
* Decouples Whitelist.Class from adding a PainlessClass directly
* Adds a second version of addPainlessClass that is intended for use to add future
defaults in a follow PR
This change also fixes the method and field caches by storing Classes instead of Strings
since it would technically be possible now that the whitelists are extendable to have
different Classes with the same name. It was convenient to add this change together
since some of the new constants are shared.
Note the changes are largely mechanical again where all the code behavior should
remain the same.
When building custom tokenfilters without an index in the _analyze endpoint,
we need to ensure that referring filters are correctly built by calling
their #setReferences() method
Fixes#32154
This change adds two contexts the execute scripts against:
* SEARCH_SCRIPT: Allows to run scripts in a search script context.
This context is used in `function_score` query's script function,
script fields, script sorting and `terms_set` query.
* FILTER_SCRIPT: Allows to run scripts in a filter script context.
This context is used in the `script` query.
In both contexts a index name needs to be specified and a sample document.
The document is needed to create an in-memory index that the script can
access via the `doc[...]` and other notations. The index name is needed
because a mapping is needed to index the document.
Examples:
```
POST /_scripts/painless/_execute
{
"script": {
"source": "doc['field'].value.length()"
},
"context" : {
"search_script": {
"document": {
"field": "four"
},
"index": "my-index"
}
}
}
```
Returns:
```
{
"result": 4
}
```
POST /_scripts/painless/_execute
{
"script": {
"source": "doc['field'].value.length() <= params.max_length",
"params": {
"max_length": 4
}
},
"context" : {
"filter_script": {
"document": {
"field": "four"
},
"index": "my-index"
}
}
}
Returns:
```
{
"result": true
}
```
Also changed PainlessExecuteAction.TransportAction to use TransportSingleShardAction
instead of HandledAction, because now in case score or filter contexts are used
the request needs to be redirected to a node that has an active IndexService
for the index being referenced (a node with a shard copy for that index).
Several pieces of data in PainlessClass cannot be passed in at the time the
PainlessClass is created so it must be "frozen" after all the data is collected. This means
PainlessClass is currently serving two functions as both a builder and a set of data. This
separates the two pieces into clearly distinct values.
This change also removes the PainlessMethodKey in favor of a simple String. The goal is
to have the painless method key be completely internal to the PainlessLookup eventually
and this simplifies the way there. Note that this was added since PainlessClass and
PainlessClassBuilder were already being changed instead of a follow up PR.
When building the PainlessMethods and PainlessFields they stored a reference to a
PainlessClass. This reference was prior to "freezing" the PainlessClass so the data was
both incomplete and mutable. This has been replaced with a target java class instead
since the PainlessClass is accessible through a java class now and it requires no special
modifications to get around a chicken and egg issue.
Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.
IT will be covered in a subsequent PR
Currently the `keep_types` token filter includes all token types specified using
its `types` parameter. Lucenes TypeTokenFilter also provides a second mode where
instead of keeping the specified tokens (include) they are filtered out
(exclude). This change exposes this option as a new `mode` parameter that can
either take the values `include` (the default, if not specified) or `exclude`.
Closes#29277
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes most of the calls not in X-Pack to their new versions.
The "source" field in SSource seems unused. If removed, it can also be removed
from the ctor, which in turn makes is possible to delete the sourceText in the
Walker class.
* Cleanup Duplication in `PainlessScriptEngine`
* Extract duplicate building of compiler settings to method
* Remove dead method params + dead constant in `ScriptProcessor`
This is related to #27260. It adds the SecurityNioHttpServerTransport
to the security plugin. It randomly uses the nio http transport in
security integration tests.
* Replace Ingest ScriptContext with Custom Interface
* Make org.elasticsearch.ingest.common.ScriptProcessorTests#testScripting more precise
* Don't mock script factory in ScriptProcessorTests
* Adjust mock script plugin in IT for new API
Because this is a static method on a public API, and one that we encourage
plugin authors to use, the method with the typo is deprecated in 6.x
rather than just renamed.
This change adds Expected Reciprocal Rank (ERR) as a ranking evaluation metric
as descriped in:
Chapelle, O., Metlzer, D., Zhang, Y., & Grinspan, P. (2009).
Expected reciprocal rank for graded relevance.
Proceeding of the 18th ACM Conference on Information and Knowledge Management.
https://doi.org/10.1145/1645953.1646033
ERR is an extension of the classical reciprocal rank to the graded relevance
case and assumes a cascade browsing model. It quantifies the usefulness of a
document at rank `i` conditioned on the degree of relevance of the items at ranks
less than `i`. ERR seems to be gain traction as an alternative to (n)DCG, so it
seems like a good metric to support. Also ERR seems to be the default optimization
metric used for training in RankLib, a widely used learning to rank library.
Relates to #29653
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `module/repository-url` project to use the new
versions.

This change adds support for template snippet (e.g. {{foo}}) resolution
in the date_index_name processor. The following configuration options
will now resolve a templated value if so configured:
* index_name_prefix (e.g "index_name_prefix": "myindex-{{foo}}-")
* date_rounding (e.g. "date_rounding" : "{{bar}}")
* index_name_format (e.g."index_name_format": "{{baz}}")
* Fix assertIngestDocument wrongfully passing
* Previously docA being subset of docB passed because iteration was over docA's keys only
* Scalars in nested fields were not compared in all cases
* Assertion errors were hard to interpret (message wasn't correct since it only mentioned the class type)
* In cases where two paths contained different types a ClassCastException was thrown instead of an AssertionError
* Fixes#28492
* Handle missing values in painless
Throw an exception for `doc['field'].value`
if this document is missing a value for the `field`.
For 7.0:
This is the default behaviour from 7.0
For 6.x:
To enable this behavior from 6.x, a user can set a jvm.option:
`-Des.script.exception_for_missing_value=true` on a node.
If a user does not enable this behavior, a deprecation warning is logged on start up.

Removes support for storing scripts without the usual json around the
script. So You can no longer do:
```
POST _scripts/<templatename>
{
"query": {
"match": {
"title": "{{query_string}}"
}
}
}
```
and must instead do:
```
POST _scripts/<templatename>
{
"script": {
"lang": "mustache",
"source": {
"query": {
"match": {
"title": "{{query_string}}"
}
}
}
}
}
```
This improves error reporting when you attempt to store a script but don't
quite get the syntax right. Before, there was a good chance that we'd
think of it as a "raw" template and just store it. Now we won't do that.
Nice.

Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
This completes the removal of Painless Type. The new data structures in the definition are a map of names (String) to Java Classes and a map of Java Classes to Painless Structs. The names to Java Classes map can contain a 2 to 1 ratio of names to classes depending on whether or not a short (imported) name is used. The Java Classes to Painless Structs is 1 to 1 always where the Java Class name must match the Painless Struct name. This should lead a significantly simpler type system in Painless moving forward since the Painless Type only held redundant information since Painless does not support generics.
ingest: Introduction of a bytes processor
This processor allows for human readable byte values (e.g. 1kb) to be converted to value in bytes (e.g. 1024). Internally this processor re-uses "ByteSizeValue.parseBytesSizeValue" which supports conversions up to Long.MAX_VALUE and the following units: "b", "kb", "mb", "gb", "tb", pb".
This change also introduces a generic return type for the AbstractStringProcessor to allow for code reuse while supporting a String -> T conversion. (String -> Long in this case).
Adds a new parameter to the BlobContainer#write*Blob methods to specify whether the existing file
should be overridden or not. For some metadata files in the repository, we actually want to replace
the current file. This is currently implemented through an explicit blob delete and then a fresh write.
In case of using a cloud provider (S3, GCS, Azure), this results in 2 API requests instead of just 1.
This change will therefore allow us to achieve the same functionality using less API requests.
This commit removes some tests in the repository-s3 plugin that
have not been executed for 2+ years but have been maintained
for nothing. Most of the tests in AbstractAwsTestCase were
obsolete or superseded by fixture based integration tests.
* remove left-over comment
* make sure of the property for plugins
* skip installing modules if these exist in the distribution
* Log the distrbution being ran
* Don't allow running with integ-tests-zip passed externally
* top level x-pack/qa can't run with oss distro
* Add support for matching objects in lists
Makes it possible to have a key that points to a list and assert that a
certain object is present in the list. All keys have to be present and
values have to match. The objects in the source list may have additional
fields.
example:
```
match: { 'nodes.$master.plugins': { name: ingest-attachment } }
```
* Update plugin and module tests to work with other distributions
Some of the tests expected that the integration tests will always be ran
with the `integ-test-zip` distribution so that there will be no other
plugins loaded.
With this change, we check for the presence of the plugin without
assuming exclusivity.
* Allow modules to run on other distros as well
To match the behavior of tets.distributions
* Add and use a new `contains` assertion
Replaces the previus changes that caused `match` to do a partial match.
* Implement PR review comments
* Migrate scripted metric aggregation scripts to ScriptContext design #29328
* Rename new script context container class and add clarifying comments to remaining references to params._agg(s)
* Misc cleanup: make mock metric agg script inner classes static
* Move _score to an accessor rather than an arg for scripted metric agg scripts
This causes the score to be evaluated only when it's used.
* Documentation changes for params._agg -> agg
* Migration doc addition for scripted metric aggs _agg object change
* Rename "agg" Scripted Metric Aggregation script context variable to "state"
* Rename a private base class from ...Agg to ...State that I missed in my last commit
* Clean up imports after merge
TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
